Sources disagree on the
names and birthdates of the children.
Rebecca's obituary says there was a total of 11 children.

Notes

In 1851, Zachariah David is living in Kingston Township, Frontenac,
Ontario.

According to genealogist Wilman Davis, "Zachariah died at the age of 67
from a bad cut he received while sharpening a scythe -- a wound that
'would not heal.' Neither Zachariah nor Rebecca were educated --
there being no schools available. Yet they could speak both English
and Dutch. ... Zachariah was a religious man, a lay preacher of Wesleyan
Methodism."
